Clash of Clans Account Scam: Account Sold, Can't Log In

I am deeply frustrated and upset because of a scam related to my Clash of Clans account. Due to financial difficulties, I decided to sell my account. A person named H*** K*** convinced me they were buying it, but after I handed over my account, they blocked me and now I can’t log in. I changed my email, but I still can't access my account, and it’s clear that this person has scammed many others like me. I’ve spent years on this game, and now everything is lost. I need Supercell's immediate assistance to recover my account and stop this scammer from affecting other players. Please, help me resolve this issue!
